Rhode Island health officials are blaming dating apps, such as Tinder and Grindr, for a spike in syphilis, gonorrhea and HIV cases in the state.

Syphilis cases have spiked 79%, while gonorrhea has risen 30%, according to data from 2013 and 2014. New cases of HIV increased by 32%.

"These data send a clear signal that despite the progress we have made in reducing STDs and HIV over the years, there is more work to do," state health director Dr. Nicole Alexander-Scott said in a statement.

Officials say the spike there follows a national trend.

"High-risk behaviours include using social media to arrange casual and often anonymous sexual encounters, having sex without a condom, having multiple sex partners, and having sex while under the influence of drugs or alcohol," the statement says.
